Title: Method of Catalytic Hydration of Olefins
IPC: C07B61/00
Filed: 1968-05-30
Abstract: 1,189,256. Catalytic hydration of olefins. HIBERNIA CHEMIE G.m.b.H. 30 May, 1968 [30 May, 1967], No. 25994/68. Heading C2C. Olefins having 2 to 4 carbon atoms are catalytically hydrated by a catalyst carrier impregnated with phosphoric acid, the phosphoric acid carried out in liquid form by the reaction products being separated after leaving the reaction zone and returned to the catalyst carrier by a pipe of non-corroding material directly inside or directly outside the reaction chamber. Phosphoric acid is entrained in the gaseous state by the gases leaving the reactor, but this acid is present in only a small amount corresponding to a partial pressure which is below the saturation point and consequently gives rise to practically no corrosion in downstream apparatus. The contact reactor is lined with carbon bricks. The catalyst carriers may in addition to SiO 2  contain up to 25% of other oxides, such as Al 2 O 3 , Fe 2 O 3  and TiO 2 , while avoiding coating following parts of apparatus.

Spongy crimpable bicomponent filaments are made by extruding, side by side or eccentrically one within the other, acetone solutions of (i) an acrylonitrile/vinylidene chloride copolymer, and (ii) a different polymer. The solutions are extruded through a spinneret hole into an aqueous coagulating bath, the acetone content of the filaments is decreased to 10 wt. per cent, and the filaments are subsequently heated and stretched; (ii) may be a copolymer embodying units similar to those of (i) but in different proportions; (ii) may be cellulose acetate, styrene/ maleic anhydride copolymer, acrylate ester, or acrylate/acrylonitrile copolymer. The solution of (ii) may additionally contain (i) in admixture. The filament density may be 0À7-0À8 g./c.c. The filaments may be crimped by annealing by heating in relaxed condition at 80-150‹ C., by contact with a hot solid surface or a hot gas, vapour or liquid. In an example, solutions in acetone containing 30% (i) acrylonitrile/vinylidene chloride copolymer and 6À25% (ii) cellulose acetate also containing 22-5% (i) were extruded through 0À003 inch diameter holes into a coagulating bath of water containing 5% acetone at 50‹ C.

The undried filaments were then stretched in steam at 18 p.s.i. by 900% of their original length, and dried, while relaxed, at up to 70‹ C. The filaments were then crimped, e.g. (a) by dry heat at 120- 125‹ C., when a helical crimp developed; they were then immersed in boiling water, or saturated brine at 90‹ C., to develop the crimp; or (b) by partially crimping at 100-105‹ C. dry heat, some latent crimp being retained for development later, e.g. when in yarn or fabric.
